DESCRIPTION
These devices are a family of static P-channel MOS shift registers in three configurations. 13 All three devices include on chip recirculate. Be- 9 cause the registers are static, the clock may be stopped indefinitely in the LOW state without loss of data. Each of the registers has a single data input; data on the input is written into the register on the HIGH-to-LOW clock edge. A single recirculate control (RC) on each chip determines whether the registers on that chip are to write data in from the data inputs or recirculate the data appearing on the output. If RC is LOW, new data is written in; if RC is HIGH then the data on the output will be written back into the register input on the next clock pulse.
